We also display in Fig. REF  the projected 95% exclusion sensitivity of the
future LUX-Zepelin (LZ) experiment (solid purple line) [1]} and the astrophysical neutrino `floor'
(dashed orange line)
[2]}, [3]}, below which astrophysical neutrino backgrounds dominate (yellow region).
We see that much of the \({\tilde{\tau }_1} - \tilde{\chi }^0_{1}\)  coannihilation region and the region of its hybridization with
the \(H/A\)  funnel lie below the projected
sensitivity of the LZ experiment, and substantial portions of them also lie below the neutrino
`floor'.
On the bright side, however, we recall that the \({\tilde{\tau }_1} - \tilde{\chi }^0_{1}\) 
region, in particular, lies at relatively small values of \(m_5, m_{10}\)  and \(m_{1/2}\) , offering
greater prospects for detection at the LHC than, e.g., the \(\tilde{\chi }^\pm _{1} - \tilde{\chi }^0_{1}\)  region, so there is
complementarity in the prospects of the LHC and direct DM experiments for probing
the SUSY SU(5) GUT model, as was noted previously for other SUSY
models [4]}.
